I grow P. primulaflora in pure long fibre sphagnum moss in a 3" pot. The
pot sits in the corner of an aquarium in bright shade with rather high
humidity. The tank gets pretty warm when the sun shines on it starting in
the middle of the afternoon, but these pings sit under the opening where
they get good air circulation. What
started out as one plant a couple of years ago, is now a mass of
primulaflora which nearly hides the entire pot. They are really beautiful
when they bloom, I have as many as twenty blossoms at a time. I also
fertilize once or twice a month with either orchid fertilizer or Epiphytes
Delight brand fertilzer at 1/4 strength.
